The last Friday practice sessions of the season saw the AT&T Williams team run through their usual set-up procedures and tyre comparisons in preparation for Saturday's qualifying session and the concluding round of the Championship, the Brazilian Grand Prix on Sunday. On an unusually cold day for this time of year at Interlagos, both drivers finished practice inside a close top ten, with Nico Rosberg ending his afternoon's session in P8 and Kazuki Nakajima in P10.

Nico Rosberg: I think we've shown ourselves to be a little bit more competitive here than we have at other tracks. That doesn't necessarily mean we'll be further up the grid tomorrow, but we might be a little bit closer. We carried out some productive set-up work today which has given us some interesting results. In terms of tyres, it's pretty clear which way we'll go, which is positive as well. The direction we'll go with other variables like rear wing level will depend on the weather forecast and the likelihood of rain.

Kazuki Nakajima: Today went quite well. We made some good progress on the set-up of the car, which is positive, but we still need to find some more performance as we have to improve before qualifying tomorrow.

Sam Michael, Technical Director: A fairly standard day for us during which we worked through our scheduled tyre tests and set-up work for the race. There was a bit of light rain in the afternoon session which affected the long runs but only for ten minutes or so. We'll now spend the evening preparing for tomorrow's qualifying.
